` e speification of Letters Patent No. 12,854, dated may 15, 185:5.`

. Beit: known `that Ll-IANDEL CHAPLI'N, fof Glover, `the county of.` Orleans and lState of Vermont,have invented a new and `useful Improvement VindoweSash` Fixi tures; andI do hereby declare thatlthe sameV l is `fully described and represented in the l following specification and the accompanying drawings, letters, figures, and references Of the saidldrawings, Figure 1, denotes a :transverse `and verticalsection of aiwindow` having my inventionapplied to its frame` `and two sashes. `.FigQ` 2, is Ia longitudinal @section ofthe samefitbeing taken through the inner sash. "Fig 3; is a side view of the wi`I`1dow-frarne,`` the `rocker shaft, cams and l retractive arms of thespring friction bolts "to be` hereinafter "described .being therein represented.

. `Insuch drawingsfA,lexhibits the `window i `frame B and C, thesashes, the latter being i applied to the formerso as to be capable of beingrespectivelyiraisedfor lowered as occasion-may require. ""Above the upper sash when it is closed or `depressed toits lowest position and in the janibb-a," of the window frame, aspring locking-bearer isarranged f l fand formed asseenfatDAn Figs. 1, and 2. A similar spring bearer` E is also so applied* i `:"to the jamb of` the `framefand below the upper sash,` when `it `is closed or elevatedto its :highest position.` From` ,these` two. springs, two bentlretractive arms F, G, eX-

tend andon oppositefsidesof or, above and below a horizontal rocker shaft, H, disposed in.the, frame A, as seenin the drawings. Thearms operate respectively with two cams *For` `projections I, extended in opposite e directions from the rocker shaft. By turnf ing the `knob Il, of fthe rocker shaft in one direction, the said shaft will force one of its vcams `against one lof the retractive arms so as to cause it to move back and draw its spring rearward. So when the knob is rotated in the'opposite direction the other cam will be made to act on its retractive arm, so as to produce `a backward movement of the yspring bearer orbolt thereof. Thus by the "bolt, b, of the .bearer projects either' over or under the sash as the case may be.

` rI fhe simplicity, construction and Inode `of o-perationof vthe above specied window fastener. render it very valuable and economical in use. e

I do not claim the `application of a fric tion springvor bolt to a window frame and sash and for the purpose of either holding "by friction the said sashat any elevation within the limits of its motion or oflocking said sash so that it may notbe either raised t or lowered-from the outside of the window,

but

What I do claim is- Arranging two spring friction bolts, their retractive arms, cams, and one rocker` shaft together and with respect to two window sashes and so as to operate lin manner substantially as specified.

` In testimony whereof, I have hereunto set my" signature this eleventh day of April, A. 13.1855, V
